Fodor's Expert Review ASARCO Mineral Discovery Center & Mine Tour

This mining operations center elucidates the importance of mining to everyday life. Indoor exhibits include a walk-through model of an ore crusher, video stations that explain refining processes, and a film about how minerals are actually extracted. Outside, you can see some of the actual equipment, including a few gargantuan trucks used for hauling the stuff. The big draw, though, is the yawning open pit of the Mission Mine, some 2 miles long and 1¾ miles wide because so much earth has to be torn up to extract the 1% that is copper. It's impressive, but doesn't bolster the case the center tries to make about how environmentally conscious mining has become. Tours of the pit take a little over an hour; the last one starts at 3:30. From May to September, pit mine tours are only offered on Saturday.
